Creates a Amazon Kinesis stream. A stream captures and transports data
records that are continuously emitted from different data sources or
producers . Scale-out within an Amazon Kinesis stream is
explicitly supported by means of shards, which are uniquely identified
groups of data records in an Amazon Kinesis stream.

You specify and control the number of shards that a stream is composed
of. Each open shard can support up to 5 read transactions per second,
up to a maximum total of 2 MB of data read per second. Each shard can
support up to 1000 records written per second, up to a maximum total
of 1 MB data written per second. You can add shards to a stream if the
amount of data input increases and you can remove shards if the amount
of data input decreases.

The stream name identifies the stream. The name is scoped to the AWS
account used by the application. It is also scoped by region. That is,
two streams in two different accounts can have the same name, and two
streams in the same account, but in two different regions, can have
the same name.

CreateStream is an asynchronous operation. Upon
receiving a CreateStream request, Amazon Kinesis
immediately returns and sets the stream status to
CREATING . After the stream is created, Amazon Kinesis
sets the stream status to ACTIVE . You should perform
read and write operations only on an ACTIVE stream.

You receive a LimitExceededException when making a
CreateStream request if you try to do one of the
following:

Have more than five streams in the CREATING state at
any point in time.

Create more shards than are authorized for your account.

For the default shard limit for an AWS account, see
Amazon Kinesis Limits . If you need to increase this limit, contact AWS Support

You can use DescribeStream to check the stream status,
which is returned in StreamStatus .

A name to identify the stream. The stream name is scoped to the AWS
account used by the application that creates the stream. It is also
scoped by region. That is, two streams in two different AWS accounts
can have the same name, and two streams in the same AWS account, but
in two different regions, can have the same name.

can have the same name, and two streams in the same AWS account, but
in two different regions, can have the same name.
